Framer Studio is my favorite prototyping tool. You can take designs you’ve worked on in Photoshop or Sketch, import them to Framer Studio at the click of a button and then write simple Coffeescript to bring those designs to life.

You can check out the full Framer Studio Cheatsheet here.

And below are a few shortcuts to get you started:

⌘ I Import
⇧ ⌘ I Import Again
⌘ R Reload Preview
